Extension Cable Bently Nevada Parts Bently Nevada 21504-000-076-05-02 For 3300 XL 5-Metre Probe

The 21504-000-076-05-02 is a 5-metre (16.4 ft) XL extension cable designed to connect any 3300 XL 5 mm or 8 mm proximity probe to the 3300 XL driver. Featuring a -76 mil miniature connector, stainless-steel armor, and fluoro-polymer outer jacket, this cable offers full chemical resistance, a 150 °C temperature rating, and less than 0.5% impedance deviation. Ideal for turbines, compressors, and pumps where long cable runs or high vibration conditions exist.

• 5 m exact length - eliminates excess cable coiling and reduces installation time
• -76 mil connector - miniature 10-32 UNF design with gold-plated contacts
• Stainless-steel armor - crush-proof to 1,000 N and rodent resistant
• Fluoro-polymer jacket - resistant to oil, fuel, steam, UV, and ozone
• 3300 XL color-code - blue boot identifies as extension cable to prevent mismatches
• Wide temperature range - operates from -55 °C to +150 °C continuously
• Precise impedance tolerance - ±0.5% ensures less than 1% system accuracy
• Global certifications - CE, ATEX Cat 3, RoHS, and REACH compliant

• Gas & steam turbine shaft vibration probes
• Centrifugal compressor axial position sensors
• Pump bearing temperature + vibration combo systems
• Offshore platforms (salt-spray, UV, rodent exposure)
• High-temperature (> 100 °C) steam valve position feedback

• Probes: 3300 XL 5 mm or 8 mm, -76 thread (e.g. 330103-00-04-10-02-05)
• Drivers: 3300 XL 5 m driver, -76 input (e.g. 330180-50-05)
• System: 3500/42M, 3500/44M, 3500/45 monitor racks
• Tools: 21500-000-080 wrench, 13849-01 cable tie kit

1. Route cable - maintain > 50 mm bend radius and avoid sharp edges.
2. Connect probe - hand-tighten 10-32 UNF, then apply 1/8 turn with wrench.
3. Seal entry - use 13849-01 watertight gland for IP68 protection.
4. Verify continuity - less than 1 Ω conductor resistance, greater than 100 MΩ @ 500 V DC.
5. Calibrate system - enter 5.0 m cable length in 3500 Rack Config Utility.
